IMPRO EMENT IN EARNING-MILLS.

TO ALL WHOM IT MAY CONCERN;

Be. it kn'own that we, WlILLIAM Q. BS1, of Pleasant Rnn, in-tiie conntyof Hnnteirdon, and State of N'cw Jersey, and Grnno v LEIGH, "of Clinton,Station; in the'c'ounty and State aforesaid, have invented certain newand nsefulImprcvcments in Fitnning-Mills, ofwhich the following-isa-full, clear, and'exact description, refer ence heing hed'to theaccompanying drawings, ivhich rnake part of this specification, andi'nwhich- F'gure 1 represents a plan or top view of a fanning-mill inwhichour improvements are embodied, Figure 2 view in elevation of neside ofthe some, and I Figure 3 n vertical longitudinal section through thesame atthe line ar a: offigIL v Onrimprovements ore shown as applied toa; portable fanningmill of ordinary i'orm, theconstrnction of which isso well understood as scarcelyto require description.

The mechanism rests on fonrvvertical legs or posts, A 'A A A connectedfirmly'togetherby cross-pieces;

B B 3 B B B so as to form a stout frame.

The projecting side of the frame, B1B, serve as'han'dles. I The grain ispoured into a. hopper, G,-from which-it falls into a shaking-shoe, D,pivoted- 'nt 01 to the crossbeaim B, and suspended at its rear end, byradius bars d, from the cross-behm B, in the nsu al wsy. The part of theshoe directly beneath the honper is solid, while the rear'part isprovided with one or morescreens, E.

The shaking-shoe is vihrated laterally, by devices hereinafterdescribed.

From the screen E the grain falls on a. sieve, F, suspended fromthe'frame by radinsbars j, and vibrated longitudinallyby deviceshereinafter'describcd; The sieve E is' hinged at its rear end, byleather straps-f, to

a frame, G, suspended from the freme at its for word end by radius barsg, A riddle, Hfis attached tothe'frame. G. It will be noted that thescreen F, frame G, and riddle H, all vibrate longitiidinally, but-that,as the screen F is suspendcdcentrallyon short radius bars, while theriddle and frame aresnsp'ended-fi om long radius bnrsg at one end, theriddle will thus swing through a. longer are than the screen, and thescreen F will have a rising and falling on openin'g'end shuttingmovement, which we have found by'exnerimentpecnlierly eflicacions insepni-atingthechafl' from the grain.

The stuffi'uhich passes through the screen F and riddle H fallsnpon thecant hoard-I, and drops into the grain-her K, through an opening, it,left for that'purposc, while the heavy grain, which falls over the endof the'riddleH, passes over the inclined bottom-hoard J, end fallsthrough an opening, j. When it is ,desired'to run all the screeningsthrough this latter'opening, the'opening Isis closed by a valve-hoard,L, shownin red in fig. 3. I I 5 l D As the grain falls throughthcscr'eens and riddles, it is exposed to ablast from a fan, 'M. V Thisfan hose spur-pinion m on one end of its shaft, driven by aspur-wliecl,-N, and shaft'n, driven by n, crank, it, or in any welhknownpreper way; A crank, 0, on the other end of the fan-shaft, reciproedtesn pi tm nmflgwhich vibrates a. boll-,crank let er, P, connected with theshake-shoe D by a. link-rod, thus shaking the shoe sidewise';

A U-shaped bracket, "R, attached to and projecting-below the pitinnn O,h'esone end of abalance-lever,

.S, pivoted to it. This lever oscillates horizontally on 'a-vert-icalpivot; 8, near its-middle, secnred-to-tl 1e bottom l or cant-hoard I,while its inner end, 3', is pivoted-to a central bar, 71., (shown in redin fig. 1; the longitudinally. rockingfrnme. The lever S play-s freely,vertically,-on its pins 8 s.

By the above-described mode of construction, the shaking-shoe D andframe G; are vibrated in directions at right angles to each other bymeans of a. single pitmen, O, and the frame G'is free to rise and fallas it oscillotes without interfering with the balance-lever, which movesin o. horizontal arc.' What we claim as our invention, anddesire tosecure by Letters Patent,-is

I. The combination, substantially as set forth, of the crankedfnn-sheft,th pitman O, the helhcrdnl; lever P, which sustains the rear end of thepitmon, the lafterally-vibrnting shaking-shoe D, thelongitudinally-vibrating 3 screen-frame G, and thehorizontally-oscilldtingiBalance-level?S, for the purposes specified.

2. The combination,suhstantially as set'fo-rth, of 5longitudinally-vibrating scieen, F, suspended centrally from shoitradius barsf, with a. longitudiunlly-vihrating frame, G,-suspended atits fo rn'ard end by long radius bars g, and hinged atits rear encl,f,to the screen F, whereby an opening and shutting o1- risin'gnudhfalling, as well as o.- longitudinally-Vibrating moyement, isimparted to the latter, and the grain thereby thoroughly sifted 3. Thecombination, substantially as set forth, with-the pitman O, of thedepending braeket R, the balance-- lever S, and thelongitudinally-vibrating fr ame G, fnuthe, purposes set forth.

The removable deflecting-board L, arranged and operating-as set forth.In. testimony whereof,"iv.e have hereuntq subscribe-cl our names. I t
